52 Planning Your Dell OpenManage IT Assistant Installation
Determining Systems Management Protocols
One of the most important decisions you will make in planning your
IT Assistant installation is determining the protocols to use with IT Assistant.
In general, your choice of protocols is determined by the systems you want
to monitor and the respective agent protocols they support. If the systems
you want to monitor have agents that use the Simple Network Management
Protocol (SNMP), Common Information Model (CIM) or the Intelligent
Platform Management Interface (IPMI) protocols, these protocols must also
be configured in IT Assistant.
Supported Protocols
IT Assistant supports three systems management protocols: SNMP, CIM,
and IPMI. These protocols allow communication between the IT Assistant
network management station and the managed systems on your network.
For communication between IT Assistant and each managed system to occur
successfully, agents (instrumentation) must be installed on each of the
systems you want to manage. For systems management, it is strongly
recommended that you enable and configure all protocols.
NOTE: Dell OpenManage Server Administrator only sends events to IT Assistant as
SNMP traps. It does not send CIM indications for either instrumentation or storage
events from a server.
NOTE: If the appropriate protocol is not configured correctly on the managed
systems, IT Assistant will fail to classify the systems properly, which may limit the
manageability for those systems.
NOTE: The Dell|EMC storage arrays and Dell PowerVault™ Modular Disks use both
SNMP and NaviCLI protocols.
SNMP
In order to successfully perform an IT Assistant installation, you must install
and enable the operating system SNMP service.
CIM
CIM is used for managing both client and server systems. It can also be used
for monitoring server instrumentation in a network that does not allow
SNMP management.
